6 Claims. 1

This invention relates to new and useful improvements in hand weavingimplements.

This invention is an improvement of my co. pending application, SerialNo. 653,753, filed March 12, 1946, now Patent No. 2,463,365, in which Idisclosed a weaving implement comprising a board having upright guidesand a hand-.operated tool to depress certain lengths of the yarn lyingwithin thelguides to permit the passing of a needle therethrough andthus eifect weaving.

In accordance with the present invention, the number of guides isreduced about onehalf, resulting in weight and cost reduction andfacilitating operation of the yarn-depressing tool.

According to another feature of the invention, the yarn-depressing toolis arranged to depress at least one complete row of yarn at a timewithout employing both hands of the weaver.

Another feature of my invention provides for the correct alignment ofthe yarn-depressing tool with the rows of guides, without requiringparticular eifort from the weaver.

The invention will be more fully explained in the following detaileddescription, the appended claims, and the drawing, in which:

Fig. 1 is a perspective view of the weaving board and theyarn-.depressing tool on it;

Fig. 2 is a plan View of some of the guides;

Fig. 3 is a side view of the cross-piece in nonoperating position on theboard;

Fig. 4 is a front view of the cross-piece in operative position with theneedle inserted; and

Fig. 5 is a cross section of a spring-loaded plunger.

Rectangularly shaped base I of the weaving board rests on suitablesupports 2 at its four corners. A plurality of upright guides or pins 3project from the base in a square and are arranged in rows which coversubstantially the entire surface of the base. The construction andarrangement of guides 3 have been described in my copending applicationand the present guides are similar to those there described except thatthe number of guides is reduced.

The reduction in guides is accomplished by eliminating about one-halfthe guides heretofore used in the inside rows. The guides in the insiderows are staggered in adjacent rows. However, the number of guides inthe marginal rows has not been reduced and, as in my copendingapplication, the guides in opposite marginal rows of the squarecorrespond. For instance, each guide in marginal row A (Fig. 2) isaligned with a guide in the marginal row (not shown) on the oppositeside of the square. I f row A were completed, there would be thirty-twoguides in it, as well as in the opposite marginal row. 1nside rows, suchas B and C, if completed, would each have seventeen guides but, as shownin Fig. 2, the guides in adjacent rows (B and C) are staggered withrespect to one another. Each inside row has one guide for each secondguide in the marginal rows.

Yarn-depressing tool 4 is a bridgelike structure arranged to engageslidably base I and pass over guides 3. Tool 4 comprises a yoke 5 havingpedestals 6 and I mounted on feet 8 and 9. Each foot has a slot orgroove adapted to engage polished edges IIJ and II of base I. Movablecross-piece I2 extends between pedestals 6 and 1 and may be movedperpendicularly to base I. Leaf spring I3 is attached near its middle toyoke 5 and at either end to cross-piece I2 by suitable means, such asscrews I4 and I5. Cam I6 is fastened near the center of yoke 5 by shaftII and rests on top surface I8 of crosspiece I2?. Projections (notshown) at either end of cross-piece I2 fit into slots I9 and 20 ofpedestals 6 and 'I so as to guide the crosspiece when it is moved.Prongs or projections 2I extend from the bottom surface of cross-pieceI2 and are spaced so that they may engage the warp lengths of yarncrossing two rows of guides 3. The prongs 2| are moved down to engagethe yarn by rotating lever 22 of cam I6 clockwise. Cam I6 forcescross-piece I'2 down and flexes spring I3 until lever 22 is returned tothe posi tion shown in Fig. 1. Spring I3 then springsl back to normaland carries cross-piece I2 up and free of guides 3.

Although in the preferred embodiment of my invention I have shownprojections 2I adapted to mesh with four rows of guides 3v at a time, itis to be understood that tool 4 may be constructed to have projectionswhich mesh with more or less than four rows of guides 3.

Each projection 2i has tines 23 and cut-away portions 24. When the toolis in non-operative vposition on the board (Fig. 3) tines 23 clearguides 3 so that tool 4 may be moved along the board on feet 8 and 9.When lever 2'2 is rotated, projections 2I are depressed and mesh withguides 3 (Fig. 4). A needle 25 carrying the weaving lengths of yarn isinserted in one end of tool 4 and pulled through to the other end. Thisprocedure is repeated in the adjoining row of guides. After two rows arewoven the cross-piece is raised into non-operative position, the toolmoved along to the next depressions 29 (Fig. 1) and two more rows woven.This procedure is repeated until the fabric is completely woven.

Spring-pressed plungers 26 and 21 are mounted in feet 8 and 9 so thatpoints 28 (Fig. 5) register with depressions 29 along opposite edges ofbase l. Depressions 29 are spaced between the suitable rows of guides 3so that when plungers 26 and 2'! register with the depressions, tool 4will be in position to permit projections 2| to mesh with guides y3.When plungers 26 and 21 are pulled out to the position shown in dottedlines (Fig. 5), points 28 are withdrawn from depressions 29 and tool 4may be moved along surfaces lll and Il.

The laying and weaving of lengths of yarn between guides 3 are performedin the same manner as described in my copending application. Warplengths 3B (Fig. 2) are laid across the square between adjacent warpwiserows, such as D and E. Next, weft lengths 3| are laid across the squarebetween alternate transverse; rows, suchas F and G. Then, second warplengths 32 are laid across the square in rows, such as H and I, skippedby lengths 3G. Finally, second Yweft lengths 33 are Woven across thesquare by needle 25 in rows, such as J and K. Projectionszl engagne onlylengths 32 in rows J and K and depress them below the level of topsurfaces 35 of base portions 34 (Fig. l) of guides 3. When needle 25passes lengths 33 along top surfaces 35 in rows J and K, lengths 33 arealternately placed lunder lengths 3B and over lengths 32 (Fig. 2).

The marginal guides provide a continuous enclosure so that each insiderow in the square has a guide at either end around which the warp andweft lengths 39-33 may be looped, thereby permitting a fabric to beAwoven from one continuous4 length of yarn. However, the guides of theinside rows are not continuous but staggered because Iv have found thatthe warp and weft lengths may be held in position satisfactorilyl byalternate guides. The reduction in guides not only lowers themanufacturing cost of the device but speeds up its operation.

What is claimed is:

1. In a hand weaving device, a base, a plurality of evenly spacedyguides arranged on the base in rows covering substantially the entiresurface of the base for supporting lengths of yarn, the marginal guidesof said plurality of guides adapted to have lengths of yarn fastenedthereto, the number of guides in a marginal row being greater than thenumber of guides in any one inside row, and a lever operatedvtool havingprojections adapted to mesh Ywith certain rows of guides.
